Converting i7 4720hq to i7 4722hq?

Intel is going to release core i7 4720 HQ and i7 4722 HQ microprocessors - GizmoZone

The 4722hq has 200mhz less on CPU side and 50mhz less on GPU side
But the advantage is that it has a max TDP of 37W vs 47W on 4720hq

So my question is, wheather a 4720HQ can be converted to 4722HQ by underclocking?

 

More than likely, yes.

 

I am trying to get this Badboy
XOTIC PC | Sager NP8651 (Clevo P650SE) - 15.6" Gaming Notebook

And if that happens, i will surely do it.
10W is huge difference for battery right?
Not to mention the temperature drop with very little decrease in performance
Even though it is slim it has insanely good GPU temp at full load (around 60C) and around 70C (i7 4710HQ)

i will try this even if it means using Prema Bios Mod

Honestly it would be dumb to downclock your 4720HQ to this spec.. It would really limit the performance of your notebook.. If you want temperature drops, best way is to get IC Diamond thermal paste and undervolt a bit.. Don't drop the TDP limits as they'll cause your CPU to throttle and have less performance..

 

That is what i am going to experiment,and if it shows any sign of cpu throttle i will use it with default specs.

And the i7 4722HQ has the same specs as a i7 4700HQ,so their performance should be identical
And from the benchmarks, i think performance difference between 4700HQ and 4720HQ is very little,right?

But 10W decrease is around 20% power reduction,sooo i think it is worth

 

Underclocking is some form of throttling. When on battery i'm running my 4810mq at 2.0 ghz with -150mv undervolt that gave me full 60 minutes with my workload and now when at uni or work i dont have to carry my power brick.

As for undervoltin and underclocking i tested which clockspeeds im getting under full load on stock, then limited cpu to those clocks and undervolted and now when not crunching to much i have 3.3ghz of prime95 load and tdp of 37 watts. Overall system runs quieter, just as fast, cooler and if needed i can ramp it up to full speed if and when i want.

 

Good to know that it works

 

If you wanna set a battery profile, that'll be okay. But if you're using it in normal usage... you probably will run into more throttling issues. The 4722HQ having the specs of a 4700MQ means it is going to draw what a 4700MQ draws. Which means "37W TDP" is going to limit its performance. There is no special secret sauce; it's just a gimped chip for notebooks that rather keep things cool than keep performance high.
